An alternative recycling method for glass wastes  (window panes, container glass and tableware) and fly ash as new glass matrix for lead waste immobilization was proposed in the following paper. The fly ash was previously used as adsorption support for the soluble lead waste from residual waters. The fly ash with 6% Pb²⁺ together with the glass wastes and borax were used as raw materials for the investigated glasses; three sets of glass samples were synthesized corresponding to weight ratios waste glass:borax:fly ash of 1:1:1, 1:0.75:1.25 and 1:0.5:1.5 respectively. The raw materials were melt for 90 minutes at 1200°C, resulting homogenous glasses. The hydrolytically and chemical stability, and lead leechability were determined according to the American Extraction Procedure Toxicity Test, ISO 719/1985 and DIN 12116/2001 respectively. The hydrolytically stability of all the studied glasses was between 11.16-17.95 mg/g R₂O soluble, qualifying them in the HGB1 stability class. The chemical stability of all glasses, characterized by the dissolution rate was 0-0.09 mg/cm²h, depending on the glass composition. The lead leechability was 0-0.07 % of the total lead in glasses, depending on the glass composition and pH of the aggressive medium. The obtained results confirm the viability of the proposed solution for lead waste immobilization with multiple economic advantages.
